From what i gathered in research, this is what I got.

1993 GT had 215, Cobra 235
94-95 GT's had 215, Cobra 240, Cobra R 300
96-97 GT had 215, Cobra 305
98 GT had 225, Cobra 305
99 -03 GT had 260 99/01 Cobra had 320, 00 Cobra R 385

stock Vs. Stock? the early 90's...
The 4.6 engine was a new technology and the heads were a major restriction 96-98, hence the big ups in 99.
but once they get everything ironed out, the newer V6's will give the 90's 5.0's a run for their money..
Yeah, that is a common upgrade and from what i hear, the biggest for the 96-98's... try doing a search on this site for 1999 Head swap... I dont think it will let you use "PI" but thats what they are called.
Yes you can...I just bought heads, intake, headers, and whole truck load of extras off of a 2000 GT. With our years higher compression the headswap results in a bit more horsepower and torque than the 99 and up cars. Just dont go supercharging right away,...everything Ive heard is that you have to TUNE TUNE TUNE or you blow head gaskets all day long. There is not much on here for PI headswap info, but the DEC 01 MM&FF I think has the article and you can get a Haynes manual and instructions from Ford on head removal and installation. Its not something for beginners but if youve changed heads before, with some guidance and a good game plan you could do it. Its the best way to go really...that and gears.
'97 GT with 80mm C&L MAF, C<rue-Flow CAI, MAC 70mm TB, Superchip, 180 thermo, B&M Ripper, King Cobra Clutch, FRPP aluminum quad/adj cable, MAC O/R H pipe, MIL's, Flows, Granatelli Solid control arms, FRPP 4.10's, FRPP aluminum driveshaft, Fidanza aluminum flywheel, FRPP 9mm wires, TMD aluminum U/D pulleys, Steeda full length SFC's (welded in), and 17" polished aluminum Cobra wheels with Nitto 555 Extremes, Kenwood/Alpine sound. Waiting for install: PI intake.
The 99's gained 35 HP from the changes to the heads, intake, etc. But the 96-98's run flat top pistons and will bump the compression up which will result in more power. I would say anywhere from 35-45 HP, but its not just the peaks that will improve, the 99+ PI parts also imporve torque and have a higher rpm power than the 96-98's.
